MULTPLE-SOCKET WRENCH.

Application filed September 12, 1325.

Y This invention relates to socketwrenches and more particularly to types embodying a rseries of nut receiving sockets in a single tool.

One of the objects is to provide a nested series of soclrets combined in a unitary handle, each individual socket being slidable into positions for service without interference of the remaining sockets.

A further feature is in the provision of a multiple socket wrench in which all of the sockets are arranged about a common axis, movable into operative position independently, and there securely held.

Another aim is to provide a simple and compact wrench and combine an effective :operative means therewith giving ample leverage to any socket which may be desired.

These and other objects which vwill become manifest, are secured by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a longitudinal sectional view taken through the center of a wrench made in accordance with the invention.

Figure 2 is a side elevational View of the same.

Figure 3 is a transverse sectional view taken on line 3--3 of Figure 1.

Figure d is a fragmentary sectional view, similar to Figure 1, but showing one of the intermediate sockets as operatively engaged.

Figure 5 is a further fragmentary sectional view showing the innermost sockets as extended.

Referring more in-detail to the drawing, the numeral designates a generally cylindrical handle having` a central longitudinal slot 11, in which is disposed a lever 12, pivoted on a transverse pin 13, this lever be-` ing swung outward at one side when used in Y turning; the wrench, as shown in the broken lines in Figure 1.

rllhe outer end of the handle is solid and the inner end le is reduced to form a heiragon,over which is disposed ahexagonal steel tube 159 rigidly held by a pin 16.

The tube as will be seen, constitutes the outer, longest and largest of the several sockets. which are closely nested therewithin, as shown at 17, 18q 1S) and 205 thus giving tive ranges of sizes which vmay be operated by the wrench.

Serial No. 55,887.

All these several hexagonal tubes, except the outermost, are freely slidable one within another and are movable by pins 17u, 18a, 19a and 20a, set in the respective tubes and extending uniformly outward through slots 60 15b, 17h` 18b and 19h in their adjacent sides,

`these slots being formed longitudinally and in register.

Similar but narrower slots 15C, 17C, 18c and 19C are formed in lthe opposite side walls of the hexagonal tubes through which pass pins 17d, 18d, 19d and 20d fixed in their respective tubes to extend uniformly outward.

A spring detent 21 is fined on one of the walls of the outer tube 15, bent lengthwise to present a portion 22, provided with a series of angular notches 23 on its edge adapted to engage any of the pins 17d, 18d, 19d and d, this detent having an extending lug 2e by which it may be retracted when shifting the sockets.

lt is to be noted that the shape of the teeth 23 permit extension of any desired socket and prevent its retraction until the detent has been manipulated.

lt will also be seen that the several sockets are progressively shorter toward the center of the wrench and the innermost socket is provided near its operative end with a solid block 25 acting as a re-enforcement in a manner similar to the interaction of the several tubes.

Freni the foregoing it will be seen that a simple and effective wrench has been disclosed in the preferred form of its embodiment, but changes may be made therein without departing from the spirit and scope of the invention as claimed.

Having thus described our invention, and set forth its operativeness and use, what we claim as new and desire to secure by Letters Patent, is z- 1. A multiple socket wrench comprising a series of nest d hei-:agonal sockets, a slotted handle in the outer soci-ret, a lever pivoted in said handle to be extended at an angle thereto., the outer socket being lined and theinner sockets slidable therein, means for projecting a selected socket into position for use, pins in each socket extending outward y beyond the outermost socket, and spring lever having teeth to engage said pins selectively'.

Q. A multiple socket wrench comprising series of nested sockets? unitary slotted handle in the outer socket.Il means to project 1.19

any selected socket, and toothed resilient means to maintain the selected socket when projected.

3. A multiple socket wrench Comprising al series of nested sockets, said sockets oontaining slots in their opposite sides, pins ixed in each socket to extend through the slots on one side of the adjacent sockets, said pins acting as handles to inove selected sockets outward, other pins in the opposite sides of the sockets extending through the adjacent slots, and a Spring detent engageable with any of the last named pins.

In Witness whereof We have signed our naines to this specification.
